在中学物理中有一些与弹簧有关的物理问题 ,由于弹簧变形发生变化时弹力会发生变化 ,使得与弹簧连接的物体受力发生变化 ,从而使物体的运动状态变化复杂 ;但只要我们弄清其变化的临界状态 ,再通过分析受力情况便可求得结果 ;常见的与弹簧连接的物体的临界状态有以下几种 .1　弹 In the middle school physics, there are some physical problems related to the spring. As the spring deformation changes, the elastic force will change, so that the object connected with the spring will change the force, so that the movement state of the object will be complicated to change; but as long as we understand it The critical state of change can then be determined by analyzing the force conditions; the critical state of common spring-connected objects is the following.
